Safety Instructions

Always follow basic safety precautions when using electric tools to reduce the risk of fire, electric shock, and personal injury. Keep this instruction manual for future reference.

• Work Area Safety: Keep your work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
• Electrical Safety: Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Personal Safety: Always wear eye protection. Use safety glasses, goggles, or a face shield. Use hearing protection for prolonged operation. Wear a dust mask if operations create dust.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
• Battery Tool Use and Care: Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

• To remove the battery: Press the release button on the battery pack and slide it out.
• To charge: Refer to your Makita battery charger's instruction manual for proper charging procedures.

Installing Drill Bits or Driver Bits

The keyless chuck allows for quick and secure bit changes.

Operating Instructions

Selecting Speed

The tool features two mechanical speed settings:

• "1" (Low Speed): For heavy-duty applications requiring high torque, such as driving large screws or drilling large holes in tough materials. Maximum 500 RPM.
• "2" (High Speed): For faster drilling and lighter driving applications. Maximum 1900 RPM.

To change speed, slide the speed selector switch located on top of the tool. Ensure the tool is stopped before changing speeds to prevent gear damage.

Selecting Operating Mode

Rotate the mode selector ring to choose the appropriate mode for your task:

• Drill Mode (Drill Bit Icon): For drilling into wood, metal, and plastic. The clutch is disengaged, providing full power.
• Impact Drill Mode (Hammer Icon): For drilling into masonry and concrete. Provides a hammering action in addition to rotation.
• Driver Mode (Screw Icon): For driving screws. The clutch will slip when the set torque is reached, preventing overtightening or stripping. Adjust the torque setting ring for desired torque.

Drilling and Driving

Hold the tool firmly with both hands if possible, especially during high-torque applications. Position the bit on the workpiece and press the trigger switch to start. The LED job light will illuminate the work area when the trigger is pulled.

Regular maintenance ensures optimal performance and extends the life of your tool.

• Cleaning: Regularly clean the tool's ventilation openings to prevent overheating. Use a soft, damp cloth. Do not use strong detergents or solvents.
• Chuck Maintenance: Periodically clean the chuck jaws to ensure proper gripping of bits.
• Battery Care: Store batteries in a cool, dry place away from direct sunlight. Do not store fully discharged batteries for extended periods.
• Inspection: Before each use, inspect the tool for any damage, loose screws, or worn parts. If any issues are found, have the tool serviced by a qualified technician.
